I like the app, but it crashed after a few months, I guess it couldn’t store too much information. I tried to contact someone to help me with the issue, (there’s no telephone assistance available, although it says when you buy the app that there is. Credit card payment option doesn’t work either) they sent me an email suggesting I un-install the app and re-install it, I asked if I was going to loose my information by doing that. I was told no, as long as I log in into the same company with my password everything will be saved. So I did that, I managed to re-install the app I logged in and all, but none of my previous invoices or Customer’s info is there. I have to re enter all the info. Tried to contact them again to see if there’s a way to avoid having to re-enter all that info again into the app. And they just replied that if I want all my info, to access it from the Website, but I like the app, that why I bought it in the first place. Never got a reply back. In other words the customer service is terrible. Once you buy the app, you are on your own if something goes wrong. ☹️ so disappointed 😞

Hi Patty, you have created a new Billdu account instead of logging to the old one and our team is waiting for your response to our last e-mail. I am confident it can be sorted out quickly, our support team replies within few hours.


Excellent but not sure if it fits our needs

We just sent our first Estimate through the app and have paid for the full year of service. But we have two business that we would like to put on it and it seems we’re unable to add our second business so we have to go back into settings and update our email address each time. As well we run a radon Mitigation company and handyman services. With the handyman services, more times than not the client provides all necessary materials and we only need to provide a labor estimate with a description of work to be completed. We worked around what was available but would like an option to place a labor only estimate that didn’t have Items on there as we won’t have any items to provide. But it does work well with our radon Mitigation company since we do the purchasing of the materials those do need to be listed. So it’s a 50/50. I gave 4 stars because it is an excellent app with so many options for our clients and us, but does not meet the necessities of our other company nor can it be added as another company. Thank you!

Let me first start off by saying that this app has been great for me. In the past I used a form of excel (Smart Office) that I modified as a quick fix. This app is set up perfectly. The 3 things that I miss from the other was that I had the option to send outgoing mail through my gmail app which is more reliable than the standard iOS. Also I was able to send through iMessage, which helped with a few of my customers that don't check email frequently. The other being making an option for Net 10th which how most of my customers are setup. As of now I have just being doing the custom option and manual choosing the 10th of the following month. I know I'm being a little picky, but all of these greatly help me if you all could consider adding these options.
I highly recommend this to anyone creating mobile invoices.

Thank you for the feedback, I will add the NET 10 option to our wishlist and it should appear in some of our future updates. Have a great day!
